Making the Most of Free Tiers
The smart approach to free AI tools: use free tiers strategically across multiple tools rather than hitting limits on one. Start your day with Claude for writing tasks (preserves ChatGPT credits for image generation later). Use Perplexity for all research (no limits on standard searches). Use Gemini for Google Workspace tasks. Save paid upgrades for the tool you use most intensively — typically your primary writing and coding AI.
